Operating key
Controlled operation: proportional pressure (pp)
may be used in the following systems:
– Dual pipe systems with thermal valves and
– Long stretches of pipe
– Valves with large working area
– High pressure loss
– Primary circulation pumps with high pressure loss
Controlled operation: constant pressure (cp)
may be used in the following systems:
– Dual pipe systems with thermal valves and
– Delivery height < 2m
– Natural circulation (formerly gravity heating)
– With very low pressure loss
– Primary circulation pumps in systems
with low pressure loss
– Floor heating with thermostatic valves
– Single pipe heating
Non-controlled operation: constant speed (cs)
The operating point can be optimally set by adjusting
the speed (key A2) optimal.
May be used for systems with constant volume flow:
air-conditioning applications, heat pumps and boiler
feed pumps, etc.
